so this was an experience from before any updates.
I admit I spent a fair amount of time trying to visit the far out, but regrettably undetailed buildings that were on the edge of the expanse before visiting the the intended destinations. despite I still enjoyed the adventure provided. After making it up the oil rig i did figure out the car was needed. I had a feeling I did need it when i saw the ramps. but by that time i had firmly gotten the car lodged in a fat roll near the summit and auto drive was not able to help. so i had to restart. made my way up there. did what was asked of me the intended way. then proceeded the rest of the way through. i did struggle with the water but usually plunging a heavy car with an even heavier passenger doesn't end well so chugged along till i made it out and then up the mountain.
overall I did enjoy it. the longing for more is there, but i was satisfied
